  • The Membership Department creates a membership file with the necessary details of your firm, and presents the file to the Chair of the Membership Committee. The Chair will carefully review your file, and make one of the following recommendations:
  • Acceptance: Your Company has met the AGS standards to become a member and may proceed with becoming an active firm. This will include completing additional education, and possessing a binocular microscope.
  • Rejection: Your Company does not meet the requirements or standards of AGS membership at this time. You may appeal this decision in writing to the International Board of Directors. There is a two-year waiting period to re-apply if your firm is denied membership.
  • A summary of your file with the Chair’s recommendation is then submitted to the Membership Committee. The committee is a confidentially seated group of approximately 11 AGS members who are long-standing and active participants of the Society. Once a majority vote has been received, the status of your application is determined.
  • If your firm is accepted into the membership, it is considered an elected firm member of the AGS, and will move on to completing the education requirements for active firm membership status. Your firm must have at least one titleholder on staff that has completed the education requirements within two (2) years of your date of election to achieve active membership status. Active status is required to take advantage of the full membership benefits. If active status is not achieved within two years, the firm risks the membership being withdrawn.
